What is an IP Address?
The Internet Protocol Address (or IP Address) is a unique address that computing devices such as personal computers, tablets, and smartphones use to identify itself and communicate with other devices in the IP network. Any device connected to the IP network must have a unique IP address within the network. An IP address is analogous to a street address or telephone number in that it is used to uniquely identify an entity.
Today there are two versions of ip addresses, however your computer is always using one address to communicate with the internet. They are called IPV4 and IPV6 (IP version 4 and IP version 6)
